MC908QB8CDWE Datasheet PDF - Freescale

●The MC68HC908QB8 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

●Features include:

●• High-performance M68HC08 CPU core

●• Fully upward-compatible object code with M68HC05 Family

●• 5-V and 3-V operating voltages (VDD)

●• 8-MHz internal bus operation at 5 V, 4-MHz at 3 V

●• Trimmable internal oscillator

●– Software selectable 1 MHz, 2 MHz, or 3.2 MHz internal bus operation

●– 8-bit trim capability

●– ± 25% untrimmed

●– Trimmable to approximately 0.4%(1)

●• Software selectable crystal oscillator range, 32–100 kHz, 1–8 MHz, and 8–32 MHz

●• Software configurable input clock from either internal or external source

●• Auto wakeup from STOP capability using dedicated internal 32-kHz RC or bus clock source

●• On-chip in-application programmable FLASH memory

●– Internal program/erase voltage generation

●– Monitor ROM containing user callable program/erase routines

●– FLASH security
